MDD Synchronous Motors
Rated 4.1 stars (4 total reviews)
The MDD090A-N-020-N2L-130PB2 is a servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed to pair with digital drive controllers, the unit converts commanded current into rotary motion for positioning or velocity control in automated machinery. Its electromechanical layout fills the need for compact, feedback-controlled motion sources commonly found on packaging lines, material-transfer stations, and light machining centers.
At standstill the motor delivers a continuous torque of 3.7 Nm, providing sufficient holding force for moderate static loads. When commanded up to its nominal mechanical speed of 2000 min⁻¹, it maintains stable operation without exceeding thermal limits. For emergency or powered-off restraint, an integrated blocking brake supplies 11.0 Nm of retentive torque. Position and velocity data are returned through digital servo feedback, enabling closed-loop regulation by the drive. A centering diameter of 130 mm aligns the stator housing precisely against mounting surfaces, simplifying concentric installation. These electrical and mechanical points establish a power-to-size ratio suited to indexing conveyors, small gantries, and auxiliary axes that do not demand high inertia loads.
The mechanical envelope follows the 090 frame code, and the rotor length matches the series’ short “A” format, so the weight and inertia remain low for rapid acceleration. Electrical and feedback conductors exit on the Side B face through a single keyed connector, allowing quick cable changes in confined panels. Dynamic balance is rated Standard to reduce vibration across the speed range, and the cast housing is also classified Standard for general industrial environments. A shaft seal protects the bearing set from coolant or dust ingress, and the ground output shaft uses a keyway to transmit torque to pulleys or couplings. Because the brake supply and encoder lines share the plug, cabinet wiring is simplified, and on-site replacement times are shortened during scheduled service.
